Webworker imports generate error because of absence of window

🌈Hey ml5 community 🌈

→ Step 1: Describe the issue 📝

While i was trying to load ml5 via a webworker I am getting an error message due to absence of window. Since webworkers provide an isolated environment it has no access to window or other web apis. Isn't there a way to make it export without being dependent on window object. I am using a K-means classifier but it freezes the browser for 2-7 secs dependent on the case. Initial idea was using a webworker to prevent freezing of UI Thread. Do you have any suggestion or a work around for this?

Trying to import like this using webpack. Imports work fine with other libraries such as antd
ml-worker.js

import ml5 from 'ml5';

self.onmessage = ({ data: { question } }) => {
  console.log(question);
  console.log(ml5.version);
  self.postMessage({
    answer: 1, // TODO: replace with ml5
  });
};

export default null;
